Enhance the Layout component with two critical UI/UX improvements:
1. Scrollable Sidebar Navigation:
- Add overflow-y-auto to navigation area between logo and logout
- Apply flex-shrink-0 to logout section to keep it anchored at bottom
- Add min-h-0 to enable proper flexbox shrinking
- Prevents logout button from being pushed off-screen when multiple
submenus are expanded
- Custom scrollbar styling for both light and dark themes
2. Fixed Header Bar:
- Change desktop header from relative to sticky positioning
- Header remains visible at top when scrolling main content
- Move overflow control from main container to content wrapper
- Proper z-index hierarchy maintained (header z-10, sidebar z-30)
- Mobile header behavior unchanged (already fixed)
Technical Details:
- Modified Layout.tsx: 7 targeted CSS class changes
- Modified index.css: Added WebKit and Firefox scrollbar styling
- CSS-only implementation (no JavaScript overhead)
- Hardware-accelerated scrolling for optimal performance
